Two point charges (91 positive charge and q2 negative charge) have the same magnitude and they are fixed to either end of the base of an isosceles triangle, as shown in the figure. The electric field at midpoint M between the charges has a magnitude EM, and that at point P, located q1 a P M directly above the midpoint, has a magnitude Ep. The ratio of these two field magnitudes is EM/Ep = 19 a 92

Two parallel, uniformly charged, infinitely long wires carry opposite charges with a linear charge density and 59.9 cm above the plane containing the two wires? = 2.29 μC/m and are 6.77 cm apart. What is the magnitude of the electric field at a point midway between them

Three charges are at the corners of an equilateral triangle, as shown in the figure below. Calculate the electric field at a point midway between the two charges on the x-axis. (Let q1 = 2.50 ?C,q2 = 6.00 ?C,and q3 = −2.50 ?C.)

Three charges are placed on three corners of a square, as shown in the figure. Each side of the square is 24.0 cm. Compute the magnitude and direction of the electric field at the fourth corner. +40 nC 65 nC

A point charge Q = -5 C and two unknown point charges, 91 and 92, are placed as shown in the figure.

Two horizontal metal plates, each 100 mm square, are aligned 10.0 mm apart, with one above the other. They are given equal-magnitude charges of opposite sign so that a uniform downward electric field of 2 000 N/C exists in the region between them. A particle of mass 2.00 x 10-16 kg and with a positive charge of 1.00 x 10-6 C leaves the center of the bottom negative plate with an initial speed of 1.00 x 105 m/s at an angle of 37.0° above the horizontal. Describe the trajectory of the particle. Which plate does it strike? Where does it strike, relative to its starting point?
